ROPE-CLAMP.

SPECIFEGATION forming part of Letters Patent No. 734,469, dated July 21,1903. Application filed January 3, 1903. Serial No. 137,664. (No modelJTo all whom, it may concern.-

Be it knownthat I, ARTHUR ADELBERT NEWELL, a citizen of the UnitedStates, and

a resident of Mellette, in the countyof Spink and State of South Dakota,have invented a new and Improved Rope-Clamp, of which the following is afull, clear, and exact descrip-- that is to be joined to the ropewhereon the clamp is mounted and which may be used in various otherconnections, as will hereinafter appear.

The invention consists in the novel construction and combination ofparts, as is hereinafter described, and defined .in the appended claims;

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View showing the application of theimprovement. Fig. 2 is a partly-sectional side view of the rope-clampand hook adjusted toclampa rope. Fig. 3 is a like view, with theexception that parts are adjusted to release a rope, the latter beingindicated by dotted lines. Fig. 4 is. an enlarged perspective View of alatch-dog that is a novel detail of the invention, and Fig. 5 is a sideview of the clamp seen in direction of the arrow 00 in Fig. 2.

The body of the rope-clamp is preferably cast into form from metal, andconsists of an essentially tubular shell 6, convexed near one end on itsexterior and having an essentially corresponding concavity a on the samewall opposite the convex surface.

An elongated opening b is formed in the shell 6 diametrically oppositethe concavity a, the edges of the shell that define said opening beingpreferably sloped downwardly and two opposite inwardly-projectingsharpened spurs c are formed,-as is clearlyindicated by full and dottedlines in Fig. 5. 'On the concave wallof the shell 6, near the hook .7,three spaced spurs d are projected inwardly, said spurs being suitablyspaced apart, as shown in Fig. 5.

From the upper termination of the sloped edges 6' the wall ofthe shellis converged somewhat, so as to diametrically reduce the open end, whichreceives the rope end A when the device is to be mounted thereon.

At or near the upper ends of the side edges 1), that define the widthand length of the opening bin the shell 6, a .latch'dog 8 is held torock, as is clearly shown in Figs. 2, 3, and 5. The dog 8 comprises anessentially L- shaped block of metal, which maybe shaped as shown inFig. 4, havingits two angularlydiverged members 8 8 braced at theirjunction by the web-wall 8.

A transverse perforation e is formed in the latch-dog 8 at the junctionof the members 8 and 8", and two opposite perforations are formed in thewall of the shell 6 to receive a pivot e, which when secured thereinafterinsertion'through the perforation 6 will dispose the members 8 8projected inwardly and free to receive rocking adjustment.

A preferably V-shaped notch g is formed in the free end of the member 8,and a like notch h is produced in the free end of the member 8 of thelatch-dog 8. Preferably the member S is of somewhat greater length thanthe member 8 and the longer member of the latch-dog may be rocked, so asto project it out of the shell 6 or be disposed within the same as shownin the drawings.

In the application of the device to a line or rope for service thelatch-dog'S is adjusted as shown in Fig. 3, which will afford a clearpassage through the shell 6 for the'insertion of the rope Atherethrough; When the shell I00 6 is positioned on the rope A at adesired point, the latch-dog 8 is rocked, so as to press the member 8against the rope A and force the latter into contact with the side ofthe shell that is opposite the dog.

The partial rotation of the longer limb or member 8 in the direction ofthe arrow at in Fig. 3 by pressure on it, whereby to introdoes theshorter member 8" within the shell 6, as described, serves to rock thelonger limb 8 into contact with the rope A, as shown in Fig. 2.

From the relative positions had by the members 8 S of the latch-dog whenit is adjusted as shown in Figs. 1 and 2 the rope A will be pressedtoward the concavity a in the shell 6 and be forced into engagement withthe spurs a (Z therein, which will prevent the shell 6 from slipping onthe rope, and it will be seen that if the rope is held at a point abovethe shell and dra t't force is applied to the hook 7 the limb S will berocked into closer engagement with the rope and clamp the shell 6tighter upon the rope.

From the foregoing it will be manifest that the angularly-bent latch-dog8 eliteets the automatic locking of the shell 6 and hook 7 upon the ropeA by merely pressing the dog member 8 as a lever from the position shownin Fig. 3 to that indicated in Fig. 2.

When it is desired to release the clamp from the rope, the shell 6 isgrasped and the rope also below the shell and held while the shell ispressed upward. This will rock the dog 8 slightly on its pivot andcorrespondingly move the dog member 8* outward from the shell, so thatit maybe taken hold of and rocked more fully outward or into theposition shown in Fig. 3, which will release the clamp from the rope.

The improvement may also be utilized for a rope-clamp with any desiredattachment theretosuch, for example, as with a ring,

"(eases a snap-hook, a swivelsnap, or a swivel, as may be desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A rope-elamp, com prising a shell having anelongated opening at one side extending through the lower end thereof, arearwardlyturned hook at the lower end of said shell forming thetermination thereof, the shell having a concavity on its rear sideopposite the lower end of the elongated opening, spurs in the concavity,and an L-shaped dog pivoted to rock at the upper end of the elongatedopening with its short arm normally extending transversely of thecentral opening of the shell to engage the rope therein and its longerarm extending downwardly in said elongated opening at the side of theshell, to a point opposite said spurs, and adapted to swing intoengagement with the rope to clamp the same into engagement with thespurs, the free ends of the L-shaped dog being each pro: vided with alarge notch adapted to embrace a portion of the circumference of therope to more firmly engage the same.

2. A rope-clamp, comprising an elongated shell having an opening in oneside extended to one end thereof, and also having a concavity near saidend opposite the opening, spurs in the concavity near each end thereof,an integral hook on the shell below the concavity, and a substantiallyL- shaped dog pivoted atits angle in the shell at its opening, said doghaving its members notched at their free ends to engage a rope.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
